Abstract:	In vivo studies concerning the function of human hematopoietic stem cells (HSC) are limited by relatively low levels of engraftment and the failure of the engrafted HSC preparations to differentiate into functional immune cells after systemic application. In the present paper we describe the effect of intrahepatically transplanted CD34(+) cells from cord blood into the liver of newborn or adult NOD/SCID mice on organ engraftment and differentiation. Analyzing the short and long term time dependency of human cell recruitment into mouse organs after cell transplantation in the liver of newborn and adult NOD/SCID mice by RT-PCR and FACS analysis, a significantly high engraftment was found after transplantation into liver of newborn NOD/SCID mice compared to adult mice, with the highest level of 35% human cells in bone marrow and 4.9% human cells in spleen at day 70. These human cells showed CD19 B-cell, CD34 and CD38 hematopoietic and CD33 myeloid cell differentiation, but lacked any T-cell differentiation. HSC transplantation into liver of adult NOD/SCID mice resulted in minor recruitment of human cells from mouse liver to other mouse organs. The results indicate the usefulness of the intrahepatic application route into the liver of newborn NOD/SCID mice for the investigation of hematopoietic differentiation potential of CD34(+) cord blood stem cell preparations.
